Children's recognition of time in the causes and cures of physical and emotional reactions to illnesses and injuries

The present set of studies examined children's and college students' recognition of the role of time in the manifestation of causes and cures for illnesses and injuries. In Study 1, participants ranging from 4‐year‐olds through college students were presented with biological, moral, psychological, and irrelevant causes for illness symptoms and were asked how much time elapsed between the cause and the symptom. They were also asked if medicine would make the person feel better and if so how much time elapsed between taking the medicine and feeling better. Study 2 replicated Study 1 with 4‐ and 5‐year‐olds. Study 3 examined whether 4‐ and 5‐year‐olds and college students could differentiate between physical and emotional reactions to illnesses and injuries, with regard to time course. Overall, young children underestimate how long it takes for illness symptoms to emerge (expecting them to result right away following exposure to contamination). Nonetheless, children generated longer timelines for biological cures than biological causes. Moreover, 4‐ and 5‐year‐olds expect physical and emotional reactions to follow different time courses. These results suggest that young children have a nascent expectation that biological events are distinct from non‐biological events, in how they unfold over time.
